Greets. G-L42 is most common SNP of all G2a's in the Western Balkan. To be precise it's L42>YSC33 subclade. It possibly arrived here with some Celtic population in the time of the Urnfield culture, since our lowest known snp is YSC33* (fow now). Here it's most common among Serbs, especially in the eastern Herzegovina region near Trebinje, some areas in Montenegro and among Krajina Serbs (which roots are in Herzegovina). Are you tested on FTDNA or some other company?
Here we are on current L42 tree.
